TheLaTeXLab - Citations & Bibliography

TheLaTeXLab - Citations & Bibliography is a WordPress citation plugin and bibliography plugin for academic bloggers, PhD students, postdocs, and research labs. Easily add citations and a bibliography in your WordPress website: paste a DOI, PubMed ID, ISBN, or arXiv ID and get a clean in-text citation and automatically generate a bibliography in APA, MLA, Chicago, IEEE, Vancouver, and other citation styles. Perfect for academic blogs, university websites, research group websites, online journals, and personal publication pages. A modern, actively maintained citation tool, it works as an up-to-date citation and BibTeX plugin for WordPress. It runs in both the block editor (Gutenberg) and the Classic Editor, and it does not lock your content: deactivate the plugin and your in-text citations stay readable as plain text. If you have been looking for an easy way to cite research papers and sources in WordPress, or to turn a DOI into a citation and bibliography, this is the plugin for it. Full documentation and a step-by-step guide on how to use the plugin: TheLaTeXLab - Citations & Bibliography documentation and how-to guide. Insert citations from identifiers

• DOI to BibTeX: paste a DOI, get the verified record from CrossRef.
• PubMed to BibTeX: paste a PubMed ID (PMID) or PMC ID.
• ISBN to BibTeX: paste an ISBN-10 or ISBN-13.
• arXiv to BibTeX: paste an arXiv ID.
• Paste a URL from doi.org, arxiv.org, PubMed, or a publisher page and the plugin extracts and verifies the identifier. A citation is produced only when it can be confidently verified against the source, never guessed.
• Import existing libraries: BibTeX (.bib) and RIS (.ris) upload.

Auto-format a bibliography Eight citation styles: APA 7, MLA 9, Chicago 17 (author-date), Harvard, IEEE, Vancouver, Nature, AMA. Selectable per post, with a site-wide default. Block editor and Classic Editor, both An "Insert Citation" block for Gutenberg and a toolbar button for the Classic Editor, sharing the same search-or-paste modal. Publications page mode A publications list block and the [thelatexlab_publications] shortcode render your references as a sortable, filterable list. Ideal for a researcher's personal site. Robust by design

• Citations are stored as portable JSON. Deactivate the plugin and in-text citations stay readable.
• Resolved metadata is cached for 30 days.
• Compatible with PHP 7.4+ and WordPress 6.0+.
• Built and designed for researchers who need fast, accurate academic citations in WordPress.

TheLaTeXLab - Professional Word to LaTeX & PDF to LaTeX Conversion This plugin is built by TheLaTeXLab, a professional LaTeX typesetting service for researchers, PhD students, and academics. Beyond WordPress citations, we help authors get their manuscripts submission-ready: Word to LaTeX, PDF to LaTeX, and thesis formatting in LaTeX to exact journal and university templates.

1. Install and activate the plugin.
2. Open Settings to pick a default citation style.
3. In the editor, use the Insert Citation block (block editor) or toolbar button (Classic Editor), paste a DOI / PubMed ID / ISBN / arXiv ID, and insert.
4. Publish. The bibliography renders at the bottom of the post, or wherever you place the bibliography block.

For bibliography formatting, the plugin uses citeproc-php. Builds shipped to WordPress.org include it; if you install from source, run "composer install" in the plugin folder.

1.0.1

• Fixed: citations are no longer dropped or merged on the front end when two citations were inserted right next to each other in the editor. The in-text marks could end up nested in the saved markup; they are now flattened so every citation is counted and rendered.
• Changed: the in-editor citation preview always shows author-date text (for example "(Smith, 2024)"), so the editor never displays a placeholder number. The front end still renders every citation in the post's selected style.
• Fixed: the same scholarly work is now stored only once, no matter how it was added (DOI, PubMed ID, ISBN, arXiv ID, manual entry, or import). References are deduplicated by work identity across all of those identifiers, so a paper added by its PubMed ID and again by its DOI no longer creates two entries. On update, existing duplicates are safely merged into one canonical reference: every citation in your posts is first repointed to the canonical entry, so no published content breaks, and only then is the redundant record removed. The merge runs in the background in resumable batches, so it is safe on large libraries.
